Even an astute connoisseur would be hard pressed to locate specific Nozkowskian tropes. There are some recurring motifs, but internal scale, texture, and mood present themselves in different coordinates. This is the more remarkable because Mr. Nozkowski’s modus operandi is so prescribed in terms of scale, medium, taste, and authentic touch.

The experience in this richly diverse exhibition is not of transition so much as consolidation: the new works, whether big loopy abstractions in fat confident brushstrokes or weirdo figuration, seem legitimate outgrowths of the precious, tight, miniaturist Siena of old.

The effect of scale, however, is to demand an attention the unglamorous, prosaic images might not otherwise command, to make moral, political claims for the importance of their subjects — in the senses both of the socially marginalized people and the issues raised.

Physical gesture means the artist’s hand is present yet transcended: there is no question that the arcs or circles are handmade, but an unforced, lyrical all-overness creates a cosmic, suprapersonal sense of order and well-being.

There is a pervasive ambivalence in Katy Grannan’s portraits: the gaze that returns the viewer’s is a mix of coyness and exhibitionism. The images themselves oscillate between similar extremes, building a visceral sense of the present through precision while succumbing to a remoteness that results from theatricality.
